Deficiency diseases are diseases in humans that are directly

Deficiency diseases are commonly associated with chronic
malnutrition. Additionally, conditions such as obesity from
overeating can also cause, or contribute to, serious health
problems. Excessive intake of some nutrients can cause acute
poisoning.

person who did not feel at ease or was uncomfortable and
not well was said to be at a dis-ease. Nowadays of course
when you talk about disease, we mean a particular
discomfort caused by a dysfunction of some part of the body.

6.Rickets
7.Kwashiorkor

5. DEFICIENCY DUE TO
CARBOHYDRATES

• CARBOHYDRATES ARE THE CHIEF
SOURCE OF ENERGY FOR THE BODY.
• THE ENERGY PRODUCED BY
CARBOHYDRATES ARE USED BY OUR
BODY TO PERFORM VARIOUS TASKS.
• DEFICIENCY OF SUFFICIENT
CARBOHYDRATES LEADS TO:
1. BODY WEAKNESS
2. LOSS OF STAMINA

6. DEFICIENCY DUE TO PROTEINS
PORTIENS ARE BODY-BUILDING FOOD. THEY CAN CAUSE SERIOUS
DISEASE,LIKE KWASHIORKOR AND MARASMIC TO SMALL
CHILDREN, IF SUFFICIENT PROTIENS ARE NOT GIVEN TO
THEM.THIS IS THE REASON WHY SMALL CHILDREN ARE ADVISED
TO TAKE PROTEIN-RICH DIET.
FOR EXAMPLE – MILK
PULSES
